NORMAN, Okla. — The No. 17 Texas Tech women’s tennis team dominated the girls doubles portion of its opening match at the Big 12 Conference Championships to secure a 4-3 victory over No. 54 Kansas State on Friday at the Headington Family Tennis Center.

With the win, Tech (19-5) will face Texas in the semifinals today at 3 p.m.

“There were a lot of reasons why we shouldn’t or couldn’t win today, and we definitely could have given in in several different areas,” Tech head coach Todd Petty said. “I was just really impressed with the character in which they played with.”

Due to impending inclement weather, the singles were played before the doubles, and the teams split those matches 3-3.

The doubles matches, however, were not that close. Teltumbde and Sanders cruised to an 8-1 victory at No. 2, then Starck and Ullathorne clinched the doubles point with an 8-2 victory over Kubickova and St. Hill at No. 3.

■ Men’s Tennis

NORMAN, Okla. — The 50th-ranked Texas Tech men’s tennis team saw its 2013 season come to a disappointing end Friday with a 4-2 loss to No. 35 TCU in the first round of the Big 12 Conference Championships.

The loss ends Tech’s season with a record of 15-11. TCU advances to face Baylor in the second round today at noon.

Because of a threat of inclement weather, the match at the Headington Family Tennis Center began with doubles, and TCU (18-8) jumped out to a 2-0 lead on victories by Orlando Superlano over Felipe Soares at No. 2 (6-4, 6-4) and Arnau Dachs over Raphael Pfister at No. 3 (1-6, 6-1, 6-0).

Tech came back with a win at No. 1 as Vitor Manzini swept Nicholas Chappell 6-4, 6-4.

The teams split the next two matches, as Tech’s Hugo Dojas fell in three sets at No. 4 to Facundo Lugones, 6-3, 4-6, 6-4, but Gabriel Wanderley for Tech beat JT Sundling 6-3, 3-6, 6-2 at No. 6.

That left it up to Tech’s Francisco Zambon at No. 5 singles to tie the match and put the win on the doubles point. Zambon and Roldolfo Bustamante split the first two matches before Bustamante won it in the final set, 6-4, 4-6, 7-5.

■ Softball

Blaire Luna held Texas Tech to just two hits in 62/3 scoreless innings, and No. 7 Texas held off a late charge by the Red Raiders for an 8-6 victory in the opener of a Big 12 Conference softball series at Rocky Johnson Field.

The Red Raiders (29-22, 3-10 in Big 12) managed just one hit through the first five innings and trailed 8-0 going into their final at-bat as Luna (23-3) walked three and struck out 10.

Tech, however, pulled to within 8-6 in the sixth, getting a two-run single from Sydnie Tapia and a two-run double from Mikey Kenney. Samantha Camello added an RBI single, and Adriana Perez pulled Tech to within 8-6 in a sacrifice fly off reliever Holly Kern.

Texas (40-6, 10-2) finally ended the inning as Luna came back in to get Texas out of the frame, then struck out Tech in order in the seventh to end the game.

Kern allowed six runs, four earned, on four hits and a walk in a third of an inning.

Texas jumped out to a 2-0 lead on Tech starter Cara Custer (13-13), who allowed six earned runs on nine hits and three walks in four innings. The Longhorns added four runs in the fifth on RBI base hits by Taylor Thom, Karina Scott and Mandy Ogle and a run-scoring error on the Red Raiders.

The Sooners, however, will have to wait until today to try to finish off an 8-0 lead after severe storms moved through the Norman area prior to the start of the ninth inning.

The teams will resume the game at noon today before starting the second game of the series at 2 p.m.

It was because of potential severe weather and an injury to Saturday starter Dillon Overton that OU coach Sunny Golloway decided to push Gray (7-1, 1.09 ERA) back to today to match up with Texas Tech right-hander Trey Masek (3-0, 0.92).

Fisher made the move work. He allowed a pair of doubles in the first — a baserunning error on Tech third baseman Jake Barrios prevented a run from scoring — then scattered five singles from the fourth through the eighth innings.

Tech’s resurgent offense from the past two games was non-existent. Leadoff hitter Brett Bell, who had reached base in nine straight plate appearances, struck out four times against Fisher. Devon Conley also struck out three times.

OU capitalized by scoring twice in the first then plated six runs from the fourth through the sixth innings.

Jack Mayfield’s three-run home run with one out in the fourth blew the game open.
